(01. 229 e1) This invention relates generally to bags formedof paper or like material and more specifically to a bag which is soconstructed and arranged as to provide a rectangular-bottom container,the predominant object of the invention being to provide an improved baghaving a rectangular bottom which instead of being formed by foldedportions of the bag forming material, as was frequently the caseheretofore, is provided by a solid unfolded portion of said bag-formingmaterial.

In the drawing, wherein is shown for the purpose of illustration,merely, two embodiments of the invention A designates a sheet of paper,or like material, of the proper dimensions to produce a bag of thedesired size. The sheet of paper A is provided with fold lines 1, 2, and3, which are extended longitudinally thereof, the fold line 2 beingextended longitudinally of the sheet at the approximate transversecenter of said sheet, and the fold lines 1 and 3 being spacedtransversely of the sheet in opposite directions with respect to thefold line 2. The sheet A is provided also with fold lines 4, 5, and 6,which are extended transversely of said sheet. The fold line 5 of thelast mentioned group of fold lines is extended transversely of the sheetA at the approximate longitudinal center thereof so that said fold line5 intersects the fold line 2 at the precise center C of the sheet A, andthe fold lines 4 and 6 are spaced longitudinally of the sheet A withrespect to and at opposite sides of the fold line 5.

Extended diagonally of the sheet A is a pair of fold lines 7 and 8. Thefold lines '7 and 8 intersect each other and cross the longitudinal foldline2 and the transverse fold line 5 at the center C of the sheet, andsaid diagonal fold lines extend to the opposite side edges of the sheetA as shown clearly in Figure l. Portions of the fold lines l.3-46 whichare located at the center of the sheet A produce a substantially squarefigure B which defines the bottom of the bag when said bag is in afolded condition, and the diagonal fold lines '7 and 8 intersect thefour corners'of the square figure B.

At the opposite ends of the longitudinally extended fold lines 1 and 3the sheet of material A preferably is notched as indicated at 9 in thedrawing and the inner end of these notches produce a more or less weakpoint at which the sheet of material may be accidentally torn. I,there-- fore, apply to the sheet of material A at the inner end of eachnotch 9 a piece of paper or other suit able material 10 which serves toreinforce the sheet of material at the points mentioned. Preferably thepieces of reinforcing material 10 are secured to the sheet of material Aat the inner face thereof by a suitable adhesive, and because of thepresence of said pieces of material the likelihood that the sheet A Willbe torn at the inner ends of the notches is rendered quite remote.

When a sheet of paper A has been prepared as illustrated in Figure 1 andit is desired to fold said sheet to produce a bag the sheet A is foldedon the fold lines 4, 5, and 6 as illustrated in Figure 2; that is tosay, the portions a and b are folded inwardly so that said portions andthe fold line 5 at the inner ends thereof are disposed between theportions c and d of the sheet A; The sheet folded as in Figure 2 is thenfolded on the fold line 2 so as to bring the right hand half of thefolded sheet to a position Where it is arranged at an approxi: materight angle with respect to the left hand half of said folded sheet asshown in Figure 3.

The opposed, parallel sections of the displaced right hand half of thefolded sheet are then spread apart as shown in Figure 4, the adjacentsections of the portions (1 and I) being folded on the portion 3 of thefold line 3 to provide the flat bottom e of the spread right hand halfof the folded sheet A, and the portion of the portions a and I) locatedto the rear of the bottom e of the spread right hand half of the foldedsheet A being extended from said bottom portion e to a point where itmerges into the sections of the portions a and b which are locatedbetween the sheet portion 0 and d of the left hand half of the foldedsheet. The bottom 6 of the spread left hand half of the folded sheettogether with the lower portions g and h of the opposed parallel sideportions 110 of said spread left hand half of the sheet are foldedupwardly, flat against the folded sheet as shown in Figure 5, the bottome being folded on the fold line 3 and the opposed side portions beingfolded on the portions 7' and 8 fold lines 7 and 8. The opposite outersections of the right hand half of the sheet which is now folded flat asshown in Figure 5 are folded inwardly so that they overlap each other attheir inner ends whereupon folding of one half of the bag is completed.

The partly folded bag is then turned over and the other half of thefolded sheet A is subjected to the same folding operation just describedwith the result that the bag will be completely folded. Adhesivematerial is then applied to the bag to secure the over-lapping portions12 at opposite sides thereof together, and also the folded portionswithin the bag at opposite sides thereof which include the rectangularportions e already referred to are secured to the adjacent side walls ofthe bag by adhesive material.

When the bag has been folded as described and secured in its foldedcondition and said bag has been opened to its effective position theresultant container is provided with a solid unfolded bottom ofrectangular shape which is defined in Figure 1 by the rectangular figureB. Bags of this type are capable of a great variety of applications andbecause of its simplicity of manufacture and efficiency in use myimproved bag fills a long felt want.

Instead of folding the sheet as just described to produce a bag such asthat illustrated in Figure 6, I may, if desired, modify the manner offolding the sheet slightly so as to produce the bag illustrated inFigure 7. In producing the bag shown in Figure 7 the sheet of bagforming material is folded in the exact manner illustrated in Figures 2,3, and 4. However, instead of folding the op posite end portions of thefolded sheet over the outer face of the portion e of the sheet so as tolocate said portion 6 at the inner sides of said opposite end portionsas illustrated in Figure 5, I will, in producing the bag shown in Figure7, fold the opposite end portions 0 and d of Figure '7 inwardly andthereafter fold the portion e of Fi ure 7 upwardly into contact with theouter faces of said portions 0' and 01. By folding the sheet as justdescribed the rectangular portions e are located at outer faces of thecompleted bag instead of at inner faces of said bag as shown in Figure6. The folded sheet illustrated in Figure 7 is secured by adhesive asalready explained to produce the completed bag.
